UNITED STATES PATENT OFFICE.

CHARLES GAYLORD- DEMING, OF KINGSTON, NEW YORK.

HINGE.

SPEGIFIGATION forming part of Letters Patent No. 663,260, dated December4, 1900.-

Application filed January 1900- sel'ial 510- 6- (NO model-J To all whomit may concern.-

Be it known that I, CHARLES GAYLORD DE- MING, a citizen of the UnitedStates, residing at Kingston, in the county of Ulster and State of NewYork, have invented certain new and useful Improvements in Hinges; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a partof this specification.

The invention relates generally to concealed or non-projecting hinges;and it consists in the construction thereof substantially as hereinaftershown, described, and claimed.

Figure 1 of the drawings is a perspective view showing my hinge with allits parts in place and in their true relative position to each other;Fig. 2, a similar View showing the hinge with the cover removed and allthe parts separate from each other.

In the drawings, A represents the median or middle piece of the hinge,which is made in T form at the middle and ends, but intermediately areleft vacant spaces, into which fit the tubular lugs 19 of the leaves BB. These lugs I) register with the holes a in the piece A, so as toreceive the pintles D, by which they are secured together, so that theleaves may turn freely. The T-piece havinga stem (1 and the plate a atright angles to each other while the stem is in the longitudinal middleof the plates the leaves will readily fold up against the stem at andparallel to each other.

I make the piano-hinge in alternate couples.

The leaves B are formed with lugs b, which project outwardly from theinner edge of the leaves and extend outwardly at right angles to theplane thereof, the inner faces of said lugs coinciding with the innerfaces of the leaves.

0 represents the cap or cover, which may be fastened in any desired wayto the plates a but so as to allow the leaves to unfold until they arein the same plane, as clearly shown in Fig. 1 of the drawings.

Having thus described all that is necessary to a full understanding ofmy invention, what I claim as new, and desire to protect by LettersPatent, is-- v The combination with a hinge comprisingin itsconstruction the leaves B B provided with spaced lugs b b projectingoutwardly from the inner faces thereof and at right angles thereto, acontinuous T-shaped link A having the spaced lugs a projectingoutwardlyon either side of the stem a, the spaces between the lugsextending across the upper face of said link and adapted to registerwith said lugs b b and pintle connections between said link and leaves,of a cover C adapted to be secured to the upper face of the link andproject over the connected lugs of the link and leaves and constructedto limit the unfolding of the leaves substantially as and for thepurpose shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES GAYLORD DEMING.
